What is the value of the expression "two less than six times the difference of a number and five" when n = 9?
1 answer:
Answer: The value of the expression when is
Step-by-step explanation:
In this case, you need to remember that:
1. Tthe word "less than" indicates a subtraction.
2. By definition, the "Difference" in the result of a subtraction.
3. The word "times" indicates multiplication,
Based on the information given above, you know that " Six times the difference of a number and five" can be expressed as:
Then, "Two less than six times the difference of a number and five" can be represented with this expression:
Now you can substitute into the expression and the evaluate in order to find the value of the expression. This is:

Answer:
h greater-than-or-equal-to negative 432
Step-by-step explanation:
* multiply each side by -24 *
IMPORTANT NOTE: when multiplying an inequality by a negative number you must flip the sign. So if the inequality sign was once facing the constant ( 18 ) then it will flip and face the variable ( h )
Thus,
h ≥-432
Which can also be expressed as h is greater than or equal to negative 432
Extra notes: You only have to flip the inequality sign if it's being multiplied by a negative number. Meaning if its multiplied by a positive number then the inequality sign does not flip.
Answer:
Step-by-step explanation:
In this problem we have a horizontal ellipse, because the major axis is the x-axis
The equation of a horizontal ellipse is equal to
where
(h,k) is the center of the ellipse
a and b are the respective vertices distances from center
we have
vertices at (7, 0) and (-7, 0)
co-vertices at (0, 1) and (0, -1)
so
The center is the origin (0.0) (The center is the midpoint of the vertices)
a=7
b=1
substitute
